Description
Technical Field
The utility model relates to the technical field of mold injection molding, in particular to a glue feeding structure.
Background
The plastic mould is a tool for producing plastic products; is also a tool for endowing plastic products with complete structure and precise dimensions. Injection molding is a process used in mass production of parts of complex shape. Specifically, the heated and melted plastic is injected into a die cavity under high pressure by an injection molding machine, and a formed product is obtained after cooling and solidification. However, in the injection molding process, a glue inlet structure is needed, but the existing glue inlet structure is easy to cause that a glue inlet is arranged on an important appearance surface of a product in the production process of the product, so that the attractive appearance of the product is influenced, and the competitiveness of the product in the market is reduced.
Disclosure of Invention
First, the technical problem to be solved
The utility model aims to provide a glue feeding structure which is used for solving the existing defects.
(II) summary of the utility model
In order to solve the technical problems, the utility model provides the following technical scheme: a glue feeding structure comprises a runner, a cup head screw, a positioning block, a straight top, a rear mold core and a dome needle, wherein the runner is arranged at the top end of the rear mold core.
Preferably, positioning blocks are arranged at two corners of the top end of the rear mold core.
Preferably, the rear mold core is provided with a straight top.
Preferably, the straight top is fixedly connected with a circular thimble through a cup head screw.
Preferably, a through hole is formed in the position of the straight top corresponding to the flow channel.
(III) beneficial effects
The utility model provides a glue feeding structure, which has the advantages that: after normal die assembly, the device is used for injecting glue, cooling, forming and die opening, the line position runs through the die-stripping stroke, the ejection system drives the round ejector pin and the straight ejector to move, so that ejection of a product is completed, after ejection is completed, a runner is pulled out from the middle, the product is taken down from the side face, and then normal reset is carried out; meanwhile, in the ejection process, the ejection work can be completed through the cooperation of the straight ejector, the cup head screw and the round ejector pin, so that ejection and glue ejection are facilitated, and meanwhile, the cost for polishing the surface of a product in the later stage is reduced.
